Friedländer's bacillus

Friedländer, Carl (1847–1887), German pathologist. Friedländer was an innovator in bacteriology. He is known chiefly for his work on the organisms associated with pneumonia. He demonstrated that cocci are invariably present in the disease. In 1882 he isolated the organism now known as Friedländer's bacillus, which he believed to be the causative agent in all cases of labor pneumonia. A year later he described a diplococcus associated with pneumonia. Friedländer is also remembered for his original description of thromboangiitis obliterans in 1876.
